In a way Judy arrays illustrate the difference between C's memory model (flat memory) and real hardware (with cache lines).

C doesn't have a flat memory model, other than within objects. ISO C doesn't even define the behavior of comparing two pointers to distinct objects for inequality, as in p0 < p1. Only exact equality: p0 == p1.
